Matrine and oxymatrine are the two major alkaloid components found in sophora roots. They are obtained primarily from Sophora japonica (kushen), but also from Sophora subprostrata (shandougen), and from the above ground portion of Sophora alopecuroides.

In China, the alkaloids are often given by injection, but this method of administration is not acceptable in the West, so oral dosing is used here instead. When taken orally, much of the oxymatrine is converted to matrine; to get high blood levels of oxymatrine, it must be given by injection. However, it is unclear whether oxymatrine is clinically more effective than matrine. Chinese researchers have also used the alkaloids in capsule form, with results that appear similar to the injection. Sophora is also administered in complex formulas made as decoctions and taken orally.

2. Applied in pharmaceutical field, sophora root extract is used for anti-bacteria, anti-inflammatory and anti-tumors.
